Answer:
240 cm², A = 300 cm², and 540 cm²
Step-by-step explanation:
1) The area of a parallelogram is A = bh, so:
A = (20)(12)
A = 240 cm²
2) Similarly, the area of a rectangle is A = bh, so:
A = (15)(20)
A = 300 cm²
3) The composite area is the sum of both the rectangle's area and the parallelogram's area, so:
240 cm² + A = 300 cm² = 540 cm²
10I^2/3
This is the answer
Answer:
<h2>
40.1 cm</h2>
solution,
BC=8.4 cm
AB=12 cm
BD=4.1 cm
We have to find out: AC ,CD
using Pythagoras theorem:
In ∆ABC ,<B=90°
Similarly,
In ∆BCD, CB=90
Perimeter:
AC+CD+AD
=14.64+9.34+(12+4.1)
=40.08
= 40.1 cm
Hope this helps...
