Answer:
Peter ate more
Step-by-step explanation:
2/8 is equal to 1/4 so peter ate double the amount of cake mary did
The length of each side of the larger square is 8 cm.
<u>Step-by-step explanation</u>:
Step 1 ;
- The combined area of two squares = 80 sq.cm
- The side of small square = x
- The side of larger square = 2x
Step 2 :
Area of the square = a^2
Area of small square + area of large square = 80
x^2 + (2x)^2 = 80
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 80/5
x^2 = 16
x = ±4
Step 3 :
Since length cannot be negative, the value of x= 4
∴ The length of the side of small square = 4cm
The length of the side of larger square = 2x = 8cm
one way to do this is to convert each fraction to same denominator ( the LCD)
Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.
4/7 = 16/28 and 3/4 = 21/28
so 4/7 < 3/4
Therfore 4/7 does lie between the 2 fractions
Answer:
the curved area would be 396cm^2
