Mrshape:
Calculate the area of the green shape in terms of r

DrayZee:

He drew a square with dimensions labeled "x". Line EF which is the diagonal of the square must therefore be xroot2.
You can get it by diving the square across the diagonal to get two triangles. Each triangle would have 2 equal sides labeled "x". Pythagorean theorem will then get you the hypothenuse of the triangle which is the diagonal of the square, which is Line EF.
I hope there's no need to explain Pythagoras as well.

You are claiming you know how to solve shape.

Oya solve this one let me see.


There are 12 chairs at a party and 4 persons are to sit on these chairs,seats 1 to 8 must be occupied and no two person should sit alternating to each other. In how many ways can they be seated?



2) A box contains 4 different black balls, 3 different red balls and 5 different blue balls. In how many ways can the balls be selected if every selection must have at least 1 black ball and one red ball?



3) 9,998,785 people attended APC's campaign in Borno state, each person gave one another a handshake. What is the total number of handshakes?



MR shape answer.....


I am waiting

Mrshape:

U are funny these are permutation and combination,
Besides I am not here to compet, but to share knowledge and bring the beauty of maths, to those who think it is only a subject to be passed to be promoted to the next class,

kings59:


Just admit you don't know it.



I am also trying to bring out the beauty of maths to those who think it is only a subject to be promoted to the next class.

Mrshape:

Do me a favor by opening your trend for this questions mention me there I will attempt.
Lets do things orderly, decently and by arrangement.

kings59:

What da hell did you solve



No formular, no gst,

Solve it like a first class student.

Darivie04:
My solution which has the same idea as Mrshape's.

Mrshape:

No2=32×15×7=3360

Mrshape:
Permit me to start with number 3
