Question

parameter and area of a rectangle whose dimensions are length length is equal to 4 + X units that is equal to 3 X + 5 units​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Length = (x+4)

breadth = (3x+5)

Perimeter = 2(L+B)

perimeter = 2(x+4+3x+5)

perimeter = 2(4x+9) = (8x+18)m

Area of rectangle = L*B

Area = (x+4)(3x+5)

Area = (3x²+5x+12x+20) = (3x²+17x+20) (Ans)
