please give me in hole solution​

Answer 1

✔✔ Answer ✔✔

⏺ Given ✏

Length ➡ (5x + 4y)
Breadth ➡ (5x - 4y)

⏺ Area ✒ Length * Breadth
✒ (5x + 4y)(5x - 4y)
✒ 5x(5x - 4y) + 4y(5x - 4y)
✒ 25x^2 - 20xy + 20xy - 16y^2
✒ 25x^2 - 16y^2


⏺ Perimeter ✒ 2(Length + Breadth)
✒ 2((5x + 4y) + (5x - 4y))
✒ 2(5x + 4y + 5x - 4y)
✒ 2(10x)
✒ 20x

Answer 2

Answer:

Area=25x²-16y²

Perimeter=20x

Step-by-step explanation:

Area= length X breadth

Area= (5x+4y)(5x-4y)

Area= 25x²-20xy+20xy-16y²

Area= 25x²-16y²

Perimeter= 2 X length + breadth

Perimeter= 5x+4y +(5x-4y)

Perimeter= 5x+4y+5x-4y

Perimeter= 20x
