Question

1. If the perimeter of a square park is 84 m , find the length of its each side .
2. The area of a rectangle is 128 sq. cm. If the length is 16cm , its breadth is ___​

Answer 1

Step-by-step explanation:

1 - Perimeter = 84

Each side = 84 / 4

= 21

2 - Breadth = x

Perimeter = 128

16 × 2 = 32

128

- 32

= 96

Answer 2

Answer:

1) 84/4= 21m

2)128/16 = 8cm

Step-by-step explanation:

1) we know

perimeter of square= side * 4

so , 84= side ×4

then side = 84/4

21m

2) we know

area of rectangle is = length × breadth

we have length= 16cm

so

128 = 16× breadth

therefore breadth = 128/16

= 8cm
