Answer:
A = 189 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = DE = 21 , h = the line from F to DE = 18 , then
A = × 21 × 18 = 10.5 × 18 = 189 yd²
Answer:
volume of the prism is in³
Step-by-step explanation:
volume of a cube with side length of :
(in)³ = in³
multiply this area by the amount of cubes:
12 × 3 × 2 = 72 cubes
in³ × 72 = = in³
volume of the prism is in³
Answer:
a=7
Step-by-step explanation:
6a-42=-7a+49
(add 7a to 6a)
13a-42=49
(add 42 to 49)
13a=91
(divide 91 by 13)
a=7
