Question

1. Find the area and per of a rectangle whose (1) length = 3 m and breadth = 2.5 ​

Answer 1

Answer:

Area of rectangle = length× breadth

= 3×2•5 = 7•5 m square

parimeter = 2(length + breadth )

2(3+2•5)

2×5•5= 16•5 m square

please make me brain list

Answer 2

Answer:

Area of rectangle is

$7.5 {m}^{2}$

Perimeter of rectangle is

$11m$

Step-by-step explanation:

Given that

Length of rectangle is 3m

Breadth of rectangle is2.5m

To find

Area of rectangle

Perimeter of rectangle

Solution

Let

l as length of rectangle

b as breadth of rectangle

a as area of rectangle

p as perimeter of rectangle

As we know that

$a = l \times b$

hence

$a = 3 \times 2.5$

by multiplication we get

$a =7.5 {m}^{2}$

Then as we know

$p = 2(l + b)$

hence

$p = 2(3 + 2.5)$

by solving multiplication and addition we get

$p = 11m$

hence

area of rectangle is

$7.5 {m}^{2}$

perimeter of rectangle is

$11m$
