Answer:
perimeter=40
area=80
Step-by-step explanation:
(I am solving without the area of a trapezoid formula btw)
convert 2/3ft to inches so 8in
then find the length adjacent to 8in (2/3ft) so we will use the Pythagorean theorem a^2+8^2=10^2
a^2+64=100
a^2=36
a=6
now lets find the area for the triangle and the one on the right side.
(8*6)/2=24
24+24=48
the combined area of both triangles is 48 so we are left off with a rectangle
8*4=32
32+48=80
the perimeter will be 10+10+4+16=40
