Answer 40 cm in the squade
The answer would be 3/16 because when multipling fractions you multiply the nomitators and put them over the denominators. So 3x1 is 3 and 4x4 is 16 so the answer is 3/16
Answer:
A = (x + 7)(x + 9)
Step-by-step explanation:
Let the width w = x
then length l = w + 4 = x + 4
Area = length x width
= x(x+4)
Then the the width is increased by 7 units and the length increased by 5 units.
w = x + 7
l = (x + 4) + 5 =x + 9
A = (x + 7)(x + 9)
