Answer:
perimetre=52 area=160m²
area of rectangle =L×B
L×B=160----------(1)
perimetre of rec=2×(L+B)
2×(L+B)=52
L+B=52/2=26
L+B=26---------(2)
from eq2
L=26-B put equation (1)
(26-B)B=160
26B-B²=160
B²-26B-160=0. by middle term split we got
B²-16B-10B-160
B(B-16)+10(B-16)
(B-16)(B+10)
B=16 B=-10 so -10 we not taken becz it is negative
put in eqtion (2)
L+16=26
L=26-16
L=10
so, lenth is 10cm and breath is 16cm
plz mark as brainliest yr....
