The * is a multiplication symbol
Answer:
False.
Step-by-step explanation:
The area = 1/2.b.h.
Answer: Infinite solutions
Step-by-step explanation:
By Pythagoreans' theorem,
7.5² = l² × b²
56.25 = l² × b²
Since l = b
56.25 ÷ 2
= l²/b²
= 28.125 mm
∴ l = √28.125
= 5.3033 mm
Area of square
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)
His estimated answer would be 120 and for number 4 it would be a) 300 b) 700 and c) 1500 hope this helped. Mark as brainliest?
