here is your answer:
1. area=14×5=70cm sq.
2. area of rhombus=basex altitude
168dmsq.= 21dm×altitude
altitude = 168dmsq./21dm =8dm
3. circumference of the circle =22/7×d
44cm = 22/7×d
diameter =44cm×(7/22)=14cm
4. circumference =2×22/7×r
132cm=44/7×r
radius =132cm×(7/44)=21cm
therefore,area =22/7×21×21=1386cmsq.
5. 0.8dm=8cm
area=8cm×8cm=64cmsq.
PLEASE MARK IT AS BRAINLIEST.
