Question

two adjacent sides of a rectangle are 5a2-2band 4a2+3b find its perimeter​

Answer 1

Hey there!

Answer:

Perimeter = 18a² + 2b

Step-by-step explanation:

Given,

Length of rectangle = 5a² - 2b

Breadth of rectangle = 4a² + 3b

Perimeter = 2( length + breadth)

                 = 2( 5a² - 2b + 4a² + 3b)

                = 2 (9a² + b)

Perimeter = 18a² + 2b

Hope It Helps You!

Answer 2

Hi there !!

Length of rectangle = 5a² - 2b

Breadth of rectangle = 4a² + 3b

Perimeter = 2(L+B)

= 2( 5a² - 2b + 4a² + 3b)

= 2 (9a² + b)

Perimeter = 18a² + 2b

Thankyou :)
