Thanks mam. It s very useful to us

i m a boy :)) not gal

If the base of a rectangle is increased by 10% and the area is unchanged, then the corresponding altitude must be decreased by :

a. 100/11%

b. 10%

c. 11%

d. 100/9%

e. 12 %

please explain anybody?

aa

correct and explain plz

let breadth=b

length(altitude)=l

Area=lb

since base increases by 10

new base b'=1.1*b

let altitute decreases by X%

new length(altitute) l'=(100-x)/100*l

new Area=l'*b'=(100-x)/100*l*1.1*b

since area is unchanged

new Area=l*b

(100-x)/100*l*1.1*b=l*b

1.1*(100-x)/100=1

110-1.1x=100

110-100=1.1x

x=10/1.1

x=100/11%
