Question

What is side two when side one is 5 mm height is 8 mm and area is 72 mm ^ 2

Answer 1

Answer:

side one=5mm

height=8mm

area =72 mm^2

let side two =x mm

so,

(5+x).8/2=72

=> (5+x).4=72

=> (5+x)=72/4=18

=> x=18-5

=> x=13

so, side two is 13 mm

Answer 2

Answer:

In Triangle

Lenght of one side = 5 mm

Height of Triangle = 8 mm

Let the other side of base

Area of Triangle = 1/2 x base x height

Area of Triangle = 72 mm²

• 1/2 x base x height = 72
• 1/2 x base x 8 = 72
• 4 x base = 72
• base = 72/4
• base = 18 mm

Lenght of other side = 18 mm

Answer = length of other side = 18 mm
