42=(2w-6)+(2w-6)+w+w
42=6w-12
54=6w
w=9
42=2l+18
24=2l
l=12
length= 12cm, width= 9cm
Answer:
9/64
Step-by-step explanation:
3 x 3 is 9 and 8 x 8 is 64 and this fraction cannot be simplified
Answer:
Length = 6 cm and width = 4 cm.
Step-by-step explanation:
Let the width be x, then the length is x + 2 cm and its area = x(x + 2).
The new width and length are x + 4 and x + 6, and the new area is
(x + 4)(x + 6).
So we have the equation:-
(x + 6)(x + 4) = x(x + 2) + 56
x^2 + 10x + 24 = x^2 + 2x + 56
10x - 2x = 56 - 24
8x = 32
x = 4 cm = width
and length = 4 + 2 = 6 cm
Answer:
multiply the numerator and the denominator of each fraction by the same number till the denominators are the same number.
