Question

L=(8-y²)m, b=(5x+2)m:,find area

Answer 1

(-5xy² + 40x - 2y² + 16)m²

Step-by-step explanation:

GIVEN :-

Length of Rectangle (L) = (8 - y²)m

Breadth of Rectangle (B) = (5x + 2)m

TO FIND :-

• The area of Rectangle

SOLUTION :-

Area = L × B

= (8 - y²) × (5x + 2) m²

= 8(5x + 2) - y²(5x + 2) m²

= 8(5x) + 8(2) - y²(5x) - y²(2) m²

= 40x + 16 - 5xy² - 2y² m²

= - 5xy² + 40x - 2y² + 16 m²

Hence,

Area of rectangle is (- 5xy² + 40x - 2y² + 16)m².

Hope it helps.
