Answer:
given that
Area of rohmbus=7.5cm
altitude=4cm.
diagonal=8cm.
we know that
Area of rohmbus =1/2×d1*d2
7.5=1/2×8×d2
7.5×2=8d2
15.0=8d2

Step-by-step explanation:
side of rhombus =7.5cm
its altitude=4cm
therefore its area will be the product of its altitude and base=7.5×4=30cm^2
it's one diagonal =8cm
therefore another formula to calculate its area =1/2d¹×d²
therefore its second diagonal will be=1/2×8×d²=30
therefore its second diagonal will be.of 7.5 centimetre
