Question

9. Find the area of an isosceles triangle each of whose equal sides measures
the side measuring 154 m.
13 cm and whose base measures 20 cm.​

Answer 1

Step-by-step explanation:

A≈15.4m²

a Side

154

m

b Base

20

cm

Unit Conversion:

a=154m

b=0.2m

Using the formulas

A=bhb

2

hb=a2﹣b2

4

Solving forA

A=1

4b4a2﹣b2=1

4·0.2·4·1542﹣0.22≈15.4m²
