(ii) perimeter of the rectangle
the length of each side of a square is 30 cm, and the length and breadth of a rectangle are
35 cm and 20 cm respectively. Find:
(i) the difference between their areas.
(ii) the difference between the perimeters of the rectangle and square.
​

Answer 1

Answer:

(I) 15 (II) 10

Step-by-step explanation:

(i) Area of square=S multiply S

30 multiply 30=90

Area of rectangle = length +breadth

35+20=75

difference between the areas =90-75=15

Perimeter of square =4 multiply Side

4 multiply 30=120

perimeter of rectangle =2 multiply (l+b)

2multiply 35+20=110

difference between the perimeter of rectangle and square =120-110=10
