Answer 1

Answer:

Step-by-step explanation:

First formula of perimeter of a rectangle?

$P = 2*(L+B)$

$P = 2*L+2*B$

$180cm = 2*L+2*35$

$180-70=2*L$

$\frac{110}{2}$$=L$

$55cm = Length$

Answer 2

Answer:

The Length of this rectangle is 55cm.

Step-by-step explanation:

Let's take length as l

Perimeter of rectangle = 2×(l + b)

180 = 2×( l + 35)

180÷2 = l + 35

90 = l + 35

90 - 35 = l

l = 55cm

Therefore length = 55cm.
