Question

find the breadth of a rectangular playground,if its area is 460m2 and the length is 23 m .Also find its perimeter​

Answer 1

Answer:

breadth=area/length as area=l×b

460/23=b therefore b=20 m

Perimeter =2(l+b)

=2×(20+23)

=2×43

=86 m

Answer 2

Step-by-step explanation:

Given ,

length = 23 m

width = ?

Area = 460 m²

We know that

Area of rectangle = length × width

• 460 m² = 23 × width
• $( \frac{460}{23} ) \: \: = \: \: width$
• width = 20 m

Area of rectangle = length × width

• → 23 × 20
• → 460 m

Perimeter of rectangle = 2 ( length + width)

• → 2 ( 23 + 20 )
• → 2 ( 43 )
• → 86 m
