Question

The perimeter of a tennis court is 160 cm. If the length is 45 cm, what is the area of the court?

Answer 1

Step-by-step explanation:

perimeter =2(length +breadth)

160 = 2( 45 + b)

160= 90+ 2b

160-90 = 2b

50÷2 =b

breadth=

= l×b

= 45×25

Area= ..

Answer 2

Answer:

Area of the tennis court is 1575cm²

Given :

Perimeter of tennis court = 160cm

Length = 45cm

Find :

Breadth and Area of the court

Step-by-step explanation :

Perimeter = 160cm

formula for perimeter = 2(l+b)

2(l+b) = 160cm

2(45cm+X) = 160

90cm+ 2x = 160

2x = 160-90

2x = 70cm

X = 70/2

X = 35cm

hence, breadth of court is 35cm

Area = l×b

= 45× 35

= 1575cm²
