Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Austin is a surfer. He took a trip to the beach during surfing season and the highest wave he caught was two feet higher than four times his height. The shortest wave he caught was four feet higher than his height. The shortest wave was three feet higher than his 7-foot surfboard is long. How tall was the highest wave Austin caught?

### Response:
 Wimbi fupi zaidi lilikuwa na urefu wa futi 7 + 3 = <<7+3=10>>10.
Austin ana urefu wa futi 10 - 4 = <<10-4=6>>6.
Hivyo, mara nne ya urefu wa Austin ni futi 4 * 6 = <<4*6=24>>24.
Wimbi refu zaidi ambalo Austin alilopata lilikuwa na urefu wa futi 24 + 2 = <<24+2=26>>26.
