5x3 + ½*(7-5)*3 = 15+3 = 18 cm²
35 cm
35cm2
Information provided in the question is not enough to answer. We can only say that for the given lengths: 7cm > 6cm > 5cm
5cm * 7cm = 35cm sq.
A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm.
1/2*5*7 = 17.5 square cm
1/2*5*7 = 17.5 square cm
you times the length by the width, say if a square was 7cm in length and 5cm in width, the area would be 35cm.
35/2 cm² 0r 17.5 cm² area = 0.5 x base x height
area= 7cm x 7cm = 49cm^2
Multiply the two numbers together - and you get 35 cm2
