The area of the trapezoid is 4.5cm
To find square numbers, you multiply the number by itself.
For example:
5 x 5 = 25
10 x 10 = 100
The question is asking to choose among the expression that represents the perimeter of the picture frame where as a rectangular picture frame has a width of 9cm and length of x cm and base on the fact, I would say that the answer would be 2x times 18. I hope you are satisfied with my answer
Answer:
D) 7.7 cm
Step-by-step explanation:
L/W=11cm/10cm=x/7cm
cross multiply to find x
10x=77
divide 10 by both sides
x=7.7
