Question

find the breadth of the rectangle whose length is 70 and perimeter 200​

Answer 1

Answer:

Step-by-step explanation:

2(b+70)=200,

2b+140=200,

2b=200-140,

2b=60,

b=60/2,

b=30.

Hope it helps you.

Answer 2

Solution;

let breadth of the rectangle is x cm

length = 70cm

perimeter = 200cm

we know that,

perimeter of the rectangle = 2(l+b)

200 = 2(70+x)

200/2 = 70+x

100-70=x

30 =x

hence, the breadth is 30cm
