Step-by-step explanation:
the surface area consists of 6 individual areas :
front and back (both are equal)
left and right (both are equal)
top and bottom
front and back are trapezoids.
the area of a trapezoid is
(base 1 + base 2)/2 × h
the bases are the 2 parallel sides.
in our case the area of one trapezoid is
(5 + 19)/2 × 12.1 = 145.2 ft²
front and back together then are 290.4 ft².
left and right are 8×14 rectangles:
8×14 = 112 ft²
together they are 224 ft².
the bottom is a 5×8 rectangle :
5×8 = 40 ft²
the top is a 19×8 rectangle :
19×8 = 152 ft²
so, the total surface area is
290.4 + 224 + 40 + 152 = 706.4 ft²
A foot has twelve inches total.
There are three fours in twelve.
So if Jeremy needs nine pieces of wood, he will need three one foot long pieces of wood from the store.
One foot=twelve inches/three=four.

Hope this helped!<3
P = a + b + c
a = shorter side
b = a + 12
c = a + 34
187 = a + (a + 12) + (a + 34)
187 = 3a + 46
187 - 46 = 3a
141 = 3a
141/3 = a
47 = a
b = a + 12 = 47 + 12 = 59
c = a + 34 = 47 + 34 = 81
lengths of 3 sides are : 47 in, 59 in, 81 in
x + 2
Step-by-step explanation:
2 ( x + 2) + 2 (x + 4) = 32
2x + 4 + 2x + 8 = 32
4x + 12 = 32
4x = 32 – 12
4x = 20
x = 5
Width of picture = 5 inches
Length of picture (x + 2) = 7 inches
Length of frame = x + 2 + 2 = 9 inches
Width of frame = x + 2 = 7 inches
