the perimeter of a rectangular sheet is 170 cm if the length is 60 cm find its bredth and also find its area of the sheet
please answer this question .
Answers
Answer:
b=25 cm
area=1500 cm²
Step-by-step explanation:
for finding the breadth
length*2
60*2
120
170-120
50
50/2
25 cm
b=25 cm
For finding area
l*b
60*25
1500 cm²
A=wl
A=wlP=2(l+w)
A=wlP=2(l+w)170=2(60+w)
A=wlP=2(l+w)170=2(60+w)170=120+w
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=w
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forA
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2= 1500cm^2
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2= 1500cm^2
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2= 1500cm^2 (A=AREA)
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2= 1500cm^2 (A=AREA)(P=PERIMETER)
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2= 1500cm^2 (A=AREA)(P=PERIMETER)(W=WIDTH)
A=wlP=2(l+w)170=2(60+w)170=120+w170-120=w50=wSolving forAA=P*l÷2-l^2= 170*60÷2-60^2= 1500cm^2 (A=AREA)(P=PERIMETER)(W=WIDTH)(L=LENGTH)
