90 degrees
the diagonals intersect at right angles
Answer:
b
Step-by-step explanation:
divide both sides of the equation by 4 to leave s by itself
Area = 0.5 x (a+b) x h
= 0.5 x (15cm + 6cm) x 1/5cm
= 0.1 x 21cm
=2.1cm^2 (2.1 centimeters squared)
35 because you can not multiply both numbers by the same number to get a smaller Greatest common multiple
