Answer:
875cm^2
Step-by-step explanation:
since opposite sides are equal
3x-y=2x+y
x=2y
y=x/2 ....(i)
thus new length=2x+y
=2x+(x/2) [using (i)]
=(4x+x)/2
l=5x/2 .....(ii)
now,
perimeter=2(l+b)=120cm
l+b=60cm
from figure and using (ii)
[5x/2]+2x-3=60
[5x+4x-6]/2=60
9x-6=120
9x=126
x=126/9
x=14 ..........(iii)
substitute (iii) in (i)
y=14/2
y=7 ...........(iv)
From figure,
length=2x+y [using (iii) and (iv)]
=2x14+7
length=35cm
breadth=2x-3
=2x14-3 ....[using(iii)]
=28-3
breadth=25cm
now,
Area=lxb
=35x25
=875cm^2
Answer:
Interest rate is 9.59%
Step-by-step explanation:
The interest rate the investment must earn in order that the death benefit could of $81,000 in 24 years' time can be derived from the rate formula in excel spreadsheet.
=rate(nper,pmt,-pv,fv)
nper is the number of years the $9,000 would be invested for i.e 24 years
pmt is the periodic additional investment which is zero
pv is the amount invested today i.e $9000
fv is the amount of death benefit payable in 24 years' time that is $81000
=rate(24,0,-9000,81000)=9.59%
