Question

37. A square and rectangle has same circumferance of 40mt. The breadth of rectangle is half of a side of the square. Determine the difference between their area.

(a) 75 mt (b) 26 mt (c) 75sq. mt (d) 25 sq. mt​

Answer 1

Answer:

hope this helps

Step-by-step explanation:

perimeter of square= 40m

let the side of the square be a so,

4a=40

a=10m

area of the square =a^2=10^2= 100m^2

b of rectangle= a/2= 5m

perimeter of rectangle = 40

2(l+b)=40

2l + 2×5 = 40

2l = 30

l= 15m

area of the rectangle = l×b = 15×5= 75m^2

difference in area= 100-75= 25m^2

thus option d is the correct answer
