Answer:
C is the answer √(8^3)
The initial value for the root is 2 and it doesn't need to be written so 8^3/2
Answer:
it's B ==35
Step-by-step explanation:
The equation for the area of a square is just one side times another side, and all sides are equal so the area is simply 4 x 4 = 16.
The first one:
the rectangle has an area of 110*140=15400
the triangle's base is (180-110)=70, and the height is 140-50=90, so the area is half of 70*90=3150
the total is 15400+3150=18550 cm²
the second one:
first, you have to find DE, which is the short leg of right triangle ADE
DE²=10²-8²=36, DE=6
DC=DE+EC=6+8=14
area of the trapazoid: (top+bottom) × height, ÷ 2
(1/2)(8+14)*8=88 ft²
