Question

find the breadth of a rectangular plot if it's perimeter is 80m and length is 30m​

Answer 1

Answer:

Breadth=25m

Step-by-step explanation:

Perimeter=2(L+B)

80 = 2(30+B)

80 = 2x30+B

$\frac{80 - 30}{2} = b$

$\frac{50}{2}$

$= 25$

Answer 2

Answer:

Area= 440m^2

Area= 440m^2Length= 22m

Area= 440m^2Length= 22mBreadth= \frac{Area}{Length}=\frac{440m^2}{22m}=20m

Area= 440m^2Length= 22mBreadth= \frac{Area}{Length}=\frac{440m^2}{22m}=20mPerimeter= 2(l+b)= 2(22m+20m)

Area= 440m^2Length= 22mBreadth= \frac{Area}{Length}=\frac{440m^2}{22m}=20mPerimeter= 2(l+b)= 2(22m+20m)=2\times42m=84m
