Answer 1

◇hi all

◇let the figure 1 be named as triangle abc
◇and the height be ad

♤base=32cm
♤height=16cm

□we know that to find area of triangle,

1/2 base × height

▪ 1 /2 × 32 × 16

▪ 16 × 16

= 256 cm Sq

similarly,
in part 2 ,

▪1/2 × 32 × 16

=256 cm Sq

now,
in the bottom triangle we will use herons formula
$\sqrt{s(s - a)(s - b)(s - c)}$
semi perimeter =(6+6+8)/2
=10

♤s-a=10-8=2
♤s-b=10-6=4
♤s-c=10-6=4

using herons formula,
area =
$\sqrt{10 \times 2 \times 4 \times 4}$
$\sqrt{2 \times 5 \times 2 \times 2 \times 2 \times 2 \times 2}$
$2 \times 2 \times 2 \sqrt{5}$
$8 \sqrt{5}$
=8× 2.23

=17.84 cm aq
