Answer:
21y² +34 yx + 8x²
Step-by-step explanation:
Area of a rectangle is given by L×W where L is length, and W is width
Given L=3y+4x
W=7y+2x
Area= (3y+4x) × (7y+2x)
3y(7y+2x) + 4x(7y+2x)
21y² + 6yx +28yx+8x²
Con esto te sacas 10
2.5 cm
2(1 + 14x)
but if you simplify the expression above it would equal to:
2 + 28x
(i hope this helps :) )
