Question

7. The area of a triangle is equal to that of a square whose each side measures 60 m. Find the sida
triangle whose corresponding altitude is 90 m.​

Answer 1

Answer:

80 m

Step-by-step explanation:

area of triangle =area of square

area of triangle=60 m ×60 m

area of triangle= 3600 m^2

3600m^2 = 1÷2× base ×altitude

3600 m^2= 1÷2 ×base×90m

3600m^2=45m ×base

3600m^2÷45m =base

80m =base
