Question

A Square and a rectangle have area of 176cm each then find side of square​

Answer 1

Let the length of rectangle be x,then width = (176/2−x) = (88−x)

∴ Area = A = x (88−x) = 88x−x²

nor for area to be maximum, (dA/dx) = 0

88 − 2x = 0

or x = 88/2 = 44

∴ maximum area = x (88−x) = 44(88−44)=44² = 1936 sq unit

Answer 2

Answer:

1936 sq unit is your answer.
