Answer :
Step-by-step explanation:
First find the area of triangle
and then the area of rectangle.
area of triangle =1/2×base×height.
=1/2×6×8
=24cm.sq
Now as we know the area we can find out one side of triangle let it be x.
answer: 24cm.sq=6+8+x
24-14=x
10cm =x.
Now area of rectangle =length ×breadth.
=14×10
=140cm.sq
therefore area of composite figure = area of triangle +area of rectangle =140+24 cm.sq
=164cm.sq
perimeter of triangle = a+b+c
=6+8+10
=24cm.
perimeter of rectangle =2×(lenght+breadth)
=2×(14+10)
=2×24=48cm
therefore perimeter =48cm+24 cm=72cm
PROBLEM:
Find the perimeter and area of the following composite figure.
