Answer:
35 cups are needed.
Step-by-step explanation:
We have to divide 8 3/4 by 1/4.
Convert to improper fraction.
8 3/4 = [(8*4) + 3] / 4
= 35 / 4.
35/4 / 1/4
= 4*35 / 4
= 35 cups.
The area of the square will be 640 sq cm.
Step-by-step explanation:
Given,
Number of strip = 4
Length (l) of each strip = 40 cm
Width (b) of each strip = 4 cm
To find the area of the inner square.
Formula
The area of rectangle = l×b
If the area of a square is A, each side will be √A
Now,
Area of each strip = 40×4 sq cm = 160 sq cm
Area of 4 strips = 160×4 sq cm = 640 sq cm
Hence,
The area of the square will be 640 sq cm.
