Answer:
225mm.sq
Step-by-step explanation:
here's your solution
=> area of figure ABFD = 15*15
= 225mm.sq
=> area of figure AECD = 15*9
= 135 mm.sq
=> area of figure BEC = 15*6
= 90mm.sq
=>area of figure ABCD = 90 + 135
= 225mm.sq
hope it helps
Answer:
180
Step-by-step explanation:
The area of a rectangle is base times height.
The area of a triangle is base times height times one-half.
So,
The area of ECBA (what the answer is) is
ECEA + EBE
The area of DCEA is AE * DA
The area of CEB is EB * CE * 0.5
But to find EB:
AE + EB = AB. And because DC is opposite to AE, and opposite sides in a rectangle are equal, AE = 9. Similarly, CE = AD = 15
Substitute the numbers we have.
AE + EB = AB
9 + EB = 15
EB = 6
Now, let's substitute the numbers we found.
DCEA = AE * DA = 9 * 15 = 135
CBE = EB * CE * 0.5 = 6 * 15 * 0.5 = 45
The total area of these two shapes is
135 + 45 = 180
So, the answer is 180.
