P = 10 m, diagonal = 26 m, keliling =...? lebar² = diagonal² - panjang² = 26² - 10² = 676 - 100 = 576 lebar = √576 = 24 m keliling = 2(p+l) = 2 (10+24) = 2 x 34 = 68 m
lebar² = diagonal² - panjang²
= 26² - 10²
= 676 - 100
= 576
lebar = √576 = 24 m
keliling = 2(p+l) = 2 (10+24) = 2 x 34 = 68 m
Diagonal = 26 m = 2×10 + 2×24
Lebar ? = 20+48
L² = D² - p² = 68 m
= 26² - 10²
= 676 - 100
L = √576
L = 24
