Answer:
√113
Step-by-step explanation:
8*8 + 7*7 = c^2
64 + 49 = c^2
√113 =C
Answer:
59
Step-by-step explanation:
z-28+2z+31=180 (angle sum property of a triangle)
3z +3 =180
3z=177
z=177/3
therefore z=59
Answer:24cm
Step-by-step explanation:
if there is 2 sides with the same like the length is 8 and 2 sides(8*2)=16
and the width is half (8/2) =4 double for 2 sides (4*2) = 8
8+16
Answer:
Width= 12 yards
Length= 24 yards
Step-by-step explanation:
Perimeter of a rectangle= 2(length + width)
Let
w= width
Twice as long as it is wide
Length= 2w
Perimeter of the rectangle= 72 yards
Perimeter of a rectangle= 2(length + width)
72 = 2(2w + w)
72 = 4w + 2w
72 = 6w
Divide both sides by 6
72/6 = w
12= w
w=12
Therefore,
Width= 12 yards
Length= 2w
=2(12)
=24 yards
