Question

The perimeter of a square and rectangle are equal . Area of square is "169cm² ." Find the area of rectangle if length is "4cm" bigger than breadth​

Answer 1

Answer:

Step-by-step explanation:

4*s = 2(l+b)

s = 2(l+b)/4

s= (l+b)/2

s² = 169

s = 13

13 = (l+b)/2

l+b = 26

l = b+ 4 ( l is 4cm bigger )

b+4+b = 26

2b = 22

b =11

l = 15

area of rectangle = l×b = 11 × 15

= 165 cm²
