To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lw
A=(5)(5)
A=25 cm²
Area of triangle=1/2bh
A=(1/2)(5)(12.5)
A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25
SA=125+25
SA=150 cm²
Answer: p= 8
Step-by-step explanation:
3p-5=19
Add 5 to both sides
3p=24
Divide 3 to both sides
p=8

Answer:
Step-by-step explanation:
10g=18.9-3.9
10g=15
g=15/10
g=1.5
So each grapefruit costs $1.50
(L+d)9=126 and the original length was 11ft so
(11+d)9=126
99+9d=126
9d=27
d=3
So he needs to extend the length by 3ft
