What is the area of this parallelogram?

a 28 m²

b 56 m²

c 84 m²

d 120 m²

The area of this parallelogram is the sum of the area of triangle DAE , area of triangle BCF and area of rectangle DEBF

Area of trianle DAE = 1/2 * base * height = 1/2 * AE * DE = 1/2 * 4 * 7 = 14 m²

Area of trianle BCF = 1/2 * base * height = 1/2 * CF * BF = 1/2 * 4 * 7 = 14 m²

Area of rectangle DEBF = length * width = FD * DE = 8 * 7 = 56 m²

Therefore, Area of the parallelogram = 14 + 14 + 56 = 84 m²

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
