Question

find the perimeter and area of a rectangle of 25m and width 15 m
​

Answer 1

☆ANSWER:

We know, perimeter of a rectangle = 2(l+b)

So, the perimeter is:

☞2×(25+15)

☞2×40

☞80 cm

Now, area of a rectangle= l×b

So, the area is:

☞25×15

☞375 cm²

Answer 2

To find : perimeter and area of rectangle .

Given : length of rectangle is $25\ m$ and width is $15\ m$ .

Solution :

• According to question we are given that length of rectangle is $25\ m$ and width is $15\ m$ .
• To find area we use following formula -
• Area of rectangle $= l\times b$
• Substituting the values we get,

• Area of rectangle = $(25\times 15 ) \ m^{2}$

                                     $= 375\ m^{2}$

• To find perimeter we use following formula -

• Perimeter of rectangle = $2 ( l + b)$

                                              $= 2 (25 + 15 ) \ m \\= 2 ( 40 ) \ m\\= 80 \ m$

Hence, area and perimeter of rectangle is $375\ m^{2}$ and $80\ m$ respectively .
