Question

URGENT! WILL GIVE BRAINLIEST!

Answer 1

Answer:

150m

Step-by-step explanation:

break up the polygon into a triangle and a rectangle.

Triangle:

to find the height of the triangle, subtract 5 from 20

height = 15m     base = 12m

$area=\frac{1}{2}bh\\ A=\frac{1}{2} (12)(15)\\A=6(15)\\A=90m$

rectangle:

$A=bh\\A=12(5)\\A=60m$

Add both areas together:

$90+60=150m$

Answer 2

Answer:

150 $m^{2}$

Step-by-step explanation:

Consider the figure as an isosceles triangle and a rectangle combined.

ISOSCELES TRIANGLE

$A = \frac{1}{2} bh$

$A = \frac{1}{2} *15*12$

A = 90

RECTANGLE

$A=lw$

$A = 5*12$

$A = 60$

60 + 90 = 150
