(0.25, 5.875) = (1/4, 5 7/8)
Answer:
52% and 7
Step-by-step explanation:
There are 25 squares of which 13 are shaded , then
× 100% = 13 × 4% = 52°
(b)
1 square represents
× 100% = 1 × 4% = 4%
Then 80% = 80% ÷ 4% = 20
That is for 80% , 20 squares require to be shaded
That is 7 more than the 13 already shaded
Perimeter = 93 x 2 + 63 x 2 = 186 + 126 = 312 feet
