Question

The perimeter of a rectangle is 26 cm and its area is 40 sq.cm.

a) Half of the perimeter =

b) If x is the breadth, length =

c) What is the equation for finding the area of the rectangle?​

Answer 1

Step-by-step explanation:

a) Half of perimeter = 26/2 = 13 cm

b) Perimeter = 2(l+x) (x = breadth and l = length)

2(l+x) = 26

l+x = 13

l = 13-x

c) Area = l*x

(13-x)*x (l = 13-x, from above)

$13x - {x}^{2}$
