Bagun datar PQRS
panjang QS = 26 cm.
panjang PW = 24 cm.
Ditanya :
A.) keliling persegi panjang PQRS.
B.) Luas PQRS.
"isi pake cara".
Diketahui :
A. Keliling = 2 . ( P+L )
=2 . ( 24 + 10 )
= 2 × 34
= 68 cm
B. Luas = P × L
= 24 × 10
=240 cm²
L = ( PS )² = 26² – 24²
= 676 - 576
=100 mm
L = 10 cm
Semoga Membantu ^_^
(PS)^2 = 26^2 – 24^2
=676-576
=100
PS = 10 cm
a. Keliling = 2(p+l)
=2 (24cm + 10cm)
=2 × 34 cm
=68 cm
b. Luas = p × l
=24 cm × 10 cm
=240 cm^2
