4. The perimeter of a rectangular pool is 56 meters. If the length of the pool is
16 meters, then find its width. What is its area?
5. The length oa rectangular wooden board is thrice its width. If the width of
the board is 120 cm, what is its length? What its perimeter and area?​

Answer 1

1. perimeter = 2( l + b )

= 2 ( 6 + 4)

= 2 × 10

= 20 cm

2. perimeter = 4a

= 4 × 5

= 20 cm

Area = a ²

= 5 × 5

= 25 cm²

3. area = 500 ft²

breadth = 20 ft

length = 500 / 20

= 25 ft

perimeter = 2( 25 + 20)

= 90 cm

4. 2 ( l + b ) = 56

l + b = 28

16 + b = 28

b = 28 - 16

= 12 cm

5. width = 120 cm

length = 360 cm

perimeter = 2( 120 + 360)

= 2 ( 480)

= 960 cm

area = 120 × 360

= 43200 cm²
