Answers
.............................................................................................
STEP 1 : Find the area of the triangle :
area = √(p)(p-a)(p-b)(p-c)
.
.............................................................................................
p = (42 + 34 + 20) ÷ 2 = 48
area = √48(48 - 42)(48-34)(48-20)
area = √56448
area = 237.59 cm²
.
.............................................................................................
STEP 2: Find height of the longest side:
Area =1/2 Base x Height
237.59 = 1/2 x 42 x Height
Height = 237.59 ÷ 21 = 11.31 cm

Answer: The area is 237.59 cm² and the height is 11.31 cm
