Question

the perimeter of rectangle is 170 if length is 35 cm find the breadth also find the area​

Answer 1

Answer:

perimeter is 170

length =35perimeter=2(l+b)

170=2(l+b)

170=2(35+b)

170=70+2b

2b=100

b=50

Area=lxb

35x50=1750ans

Answer 2

The area is "1750 cm²". Further explanation is given below.

Step-by-step explanation:

Given:

Perimeter of a rectangle, P = 170 cm

The length of a rectangle, L = 35 cm

As we know,

Perimeter = 2(L+B)

On putting the values in the above formula, we get

⇒  170 = 2(35+B)

⇒  170 = 70+2B

⇒  170-70 = 2B

⇒  100 = 2B

⇒  B = $\frac{100}{2}$

⇒  B = 50 cm

Now,

Area of a rectangle = L×B

On putting the values in the above formula, we get

⇒  Area = 35×50

⇒           = 1750 cm²
