Question

find the breadth of a rectangular plot of length 45m having perimeter 140m.also ,find its area

Answer 1

Answer:

Perimeter = 2 (length + breath)

P = 2*45 + 2*breath

P = 90+2b

140-90 = 2b

50=2b

25=b

Therefore breath = 25m

Area = ( length * breath) square units

= (25*45) squad units

= 1,125m sq

Ans= b= 25m

Area = 1,125m sq

Step-by-step explanation:

Answer 2

Answer:

Breadth = 25 m

Area = 1125 m²

Step-by-step explanation:

Perimeter = 2 [ L + B ]

= 140 m

Perimeter = 2 [ 45 + x ]

= 90 + 2x

140 - 90 = 2x

50 = 2x

2x = 50

x = 50 ÷ 2

x = 25 m

Area = L × B

= 45 × 25

= 1125 m²
