square .png Each square will have sides as 10 Each \Delta will have legs as 10 and 10 ,Hence area = \frac{1}{2}*10*10 = 50 Hope the post helps.

Abhishek009 · Answer

20*10 = 2a^2

So,  a = 10

Thus, area of each triangle will be 1/2*10*10 = 50, Answer must be (C)

By cutting the rectangular cloth in the middle from the length, we get 2 squares with sides 10 inches each.

To cut the square cloth in exactly two triangles, we cut it diagonally. We get 2 isosceles right-angled triangles with height and base as 10 inches each.

Area = 1/2 x b x h
= 1/2 x 10 x 10 
= 50 square inches

Option C

The area of the rectangle is 200. We cut it in half and then in half again, so in quarters. One quarter has an area of 50.

Answer choice C.

Since area is exactly divided we can calculate area of rectangle 10*20 = 200

and divide it by 4 = 50 (area of a traingle)
