Question

find the breath and perimeter of rectangle area =90 sq.cm length =15 cm​

Answer 1

Answer:

6cm and 42 cm

Step-by-step explanation:

Given :- Length of the rectangle = 15 cm

Area of the rectangle = 90 cm^2

To find :- Breadth of the rectangle

perimeter of the rectangle

Solution :-

As we know,

Area of rectangle = Length * Breadth

90 cm^2 = 15 cm * Breadth 90 cm^2 /15 cm = Breadth

6 cm = Breadth

Now,

Perimeter of the rectangle = 2(length + Breadth)

= 2(15 +6)cm

= 2(21)cm

= 42 cm

Hence, Breadth of the rectangle is 6cm and its perimeter is 42cm.

Answer 2

Step-by-step explanation:

perimeter=90sq.cm

length=15cm

breath=???

perimeter of rectangle=2(l+b)

90=2(15+b)

90/2=15+b

45=15+b

b=45-15

b=30
