Question

1.
If the length of a rectangle is twice its breadth and its perimeter is 300 m, then find its breadth.
d. 25 m
b. 100 m
c. 75 m
a. 50 m​

Answer 1

Answer:

a. 50 m​

Step-by-step explanation:

let the breadth =×

and the length of rectangle =2×

given , perimeter =300

2(l+b)=300

2(×+2×)=300

2(3×)=300

6×=300

×=300/6

×=50

therefore , the breadth of rectangle =50

Answer 2

Answer:

let the breath =x

and length =2x

then the perimeter=300m

2(l+b)=300

2(x+2x)=300

2×3x=300

6x=300

x=300/6

x = 50

breath = 50

and, length = 2×50 = 100
