zalisa [80]3 years ago

Answer:

c) 56 m²

Step-by-step explanation:

Area of the figure =  area of triangle + area of rectangle

Rectangle:

length = 8 m

Width = 5 m

Area = length * width

       = 8 *5

       = 40 m²

Triangle:

base (b)= 4 m

height (h) =  8 m

Area=\frac{1}{2}bh\\\\ =\frac{1}{2}*4*8\\

= 2* 8

=  16 m²

Area of the figure = 40 + 16

                                = 56 m²

Answer:

The answer to your question is FJ = 18

Step-by-step explanation:

Data

FG = 30

FH = 12

HE = 8

JH ║GE

These triangles are similar, so we can use proportions to find the length of FJ.

                            \frac{FJ}{FH} = \frac{FG}{FH + HE}

Substitution

                          \frac{FJ}{12} = \frac{30}{12 + 8}

Simplification

                         \frac{FJ}{12} = \frac{30}{20}

Solve for FJ

                        FJ = 12 \frac{30}{20}

Result

                        FJ = 18
