Question

Atriangle and a parallogram stands on the base 18 cm find the height of parallogram

Answer 1

Answer:

Step-by-step explanation:

Area of∆le=area of parallelogram

a=15,b=14,c=13

Area of ∆=√(s(s-a)(s-b)(s-c))

Where s=(a+b+c)÷2

ie,s=(15+14+13)÷2

=42÷2=21

Area of ∆=√(21×(21-15)(21-14)(21-13))

=√(21×6×7×8)

=√7056= 84

Area of ∆= area of parallelogram ,,,,,, Area of parallelogram=base×height,, Base=14, 84=14×h H=84÷14=6
