Step-by-step explanation:
(4x * 4x * 4) * (4x * 4x * 4 )
(16x * 4 ) * ( 16x *4)
16x * 16x = 256x
4 * 4 = 16
256x * 16
hope this helped a little
* = multiply
Length = l
width = 1/3 of length = l/3
perimeter = 2(l + l/3)
Answer is option B
-----------------------------------
2(l+ l/3) = 56
⇒ 8l/3 = 56
⇒ l = 3*56/8
⇒ l = 21 inch
width = 21/3 = 7inch
Area = 21*7 inch² = 147 inch²
