Question

find the perimeter of rectangle whose l=7cm b=1.5​

Answer 1

Answer:

17

Step-by-step explanation:

7 + 1.5 = 8.5

8.5 TWO TIMES BECUASE 2[l+b]

=17

not sure but here

Answer 2

Given: $l=7cm.,\ b=1.5cm.$

We have to find the perimeter of a rectangle.

As we know that the formula is used to calculate the perimeter of a rectangle is:

$P=2(l+b)$

Where,

l = length,

b = breadth

We are solving in the following way:

We have,

$l=7cm.,\ b=1.5cm.$

Now,

The perimeter of a rectangle will be:

$P=2(l+b)$

$\Rightarrow P=2(7+1.5)\\\Rightarrow P=2(8.5)\\\Rightarrow P=17cm$

Hence, the perimeter of a rectangle will be$17cm.$
