Answer:
1/7
Step-by-step explanation:
You multiply the dinominator by 3 because you are finding out how much you get if you cut 1/4 into 3 pieces that are the same size.
A is equal to 50 since 50+10=60 and 50-10=40 so that means b=10. a/b would be 50/10 which is equal to 5

Step-by-step explanation:
Bob need to paint 205 square feet.
Solution:
Length of the door = 7 ft
Breadth of the door = 5 ft
Area of the door = length × breadth
= 7 × 5
= 35
Area of the door = 35 ft²
The given image is a trapezoid.
Top base = 12 ft
Bottom base = 20 ft
Area of the trapezoid =
= 240
Area of the trapezoid = 240 ft²
Surface area to paint = Area of the trapezoid – Area of the door
= 240 ft² – 35 ft²
= 205 ft²
Hence Bob need to paint 205 square feet.
