Answer 1

Answer:

THE LENGTH OF ALTITUDE IS 8cm

Step-by-step explanation:

PARAMETERS GIVEN,

LENGTH OF FIRST PARALLEL SIDE = 19cm

LENGTH OF SECOND PARALLEL SIDE = 13cm

AREA=128cm²

SO,

LET THE LENGTH OF ALTITUDE BE x

SO,

A.T.Q.,

AREA=1/2(ALTITUDE)(a+b)

128cm²=1/2(x)(19cm+13cm)

128cm²=1/2(x)32cm²

128cm²=x*16cm²

x=128cm²/16cm²

x=8cm

I HOPE YOU UNDERSTOOD THE QUESTION!!!
